Hi, I have I think a very basic question..

I need to plot on the same graph two different data sets, one in a sampling rate of 500hz and the other one in 609 hz... and they need to be synchronized in relation to time.

the problem is that when I try to convert it to seconds I getting an unequal x and y sizes...

How can I do it?

Thanks!

If you have the Signal Processing Toolbox, I would use the resample function to downsample the 609 Hz signal to 500 Hz, then plot them. If you don’t have resample, use interp1.
